Can I have one ssl certificate for multiple domains? (iis windows 2003 server)

Hi,
I have a continuation of the question "Can I have one SSL certificate for 3 domains, IIS on a windows 2003 server?"
If the domains are as follows - domain1.com and domain2.com will the SAN cert or UC cert still work? All the examples on the related question use domain.com, domain.net. Domain1.com is our original site and we have a requirement to create a dns alias as domain2.com. Is there any way to get this to work without receiving the security error?

Highfive is so simple that setting up every meeting room takes just minutes and every employee will be able to start or join a call from any room with ease. Never be called into a meeting just to get it started again. This is how video conferencing should work!

xxx.domain1.com and yyy.domain1.com appear as two separate sites in iis. xxx.domain1.com was created as a sharepoint site and then extended as yyy.domain1.com. One site has a 'listener' in ISA and the other one doesn't. The new domain sites - xxx.domain2.com and yyy.domain2.com - were created as aliases of the two original sites in DNS. They could both point to xxx.domain1.com if this will help us get by with just one certificate. I really appreciate the help and I hope I have explained it clearly enough.
Thanks,
Sandy
